ELECTRIC-LIGHT rrrrrnnn.

Application'filed April 4, *27, Serial No. 180,672.

The invention relates to an electric light fixture, and particularly that type of fixture wherein a shade is'used Wlllcll may be'rotated to cause the light from the electric lamp to be directioinbeing also constructed in such amanner that the. shade may readily be rotated and frictionally held in any desired position to cause the light rays, to be reflected in any desired direction.

The principal object'of the invention is to provide a construction which is especially useful in hospitalswhen a subdued light from the lamp is desired and not afull floodof light. In order to inake the light inconspicuous and not disturb the patient, if the fixture is in the room, or disturb anyone, if the fixture i'sin the corridor, the fixture is preferably placed about 18 inches from the fioor with the shade in position to cause the light rays to be reflected downwardly. In case anyone should desire to use the light available from the shaded lamp, as,zfor instance, to examine in structions, a thermometer, etc;, the shade may be rotated about one-half turnand the light will then be reflected upwardly, or it may be rotated any amount and frictionally held in any desired position to cause the rays of light to be reflected where desired.

In connectionwithone of the modified con structio'ns referredto hereinafter, it an obiect of the invention to construct the fixture in such a manner that the light socket receiving member of the fixture shall have offset portions to receive an electric light bulb whichis larger than the bulbwhich could be readily used'in connection with the other fiX- tures shown and described herein, Because of the nature of the offset in the member, when the shade is rotated to a certain position the larger bulb may be inserted and removed without removing the shade or unscrewing portions of the fixture. Bymeans of the oil set member referred to, light-bulbs oflvarious standard dimensions can be used with the in vcntion.

The invention will be explained andmore clearly understood when; read in conjunction with the accompanying drawings which illustrate embodimen-tsof which the inventionis susceptible, it being obvious that changes and modifications in various details of the device may be made without departing from the spiritofthe invention as expressed in the appended claimsforming apart hereof.-

Figure 8 is a vertical sectional view ofstill another modified form of electric light firiture which employsa light socket receiving member having offset portions, and,

Figure 9 is a front elev-ational view of the light fixture shown in Figure 8, on the line 9 9 thereof, with'the lamp bulb removed and showing the lamp shade in section. The structure of the invention, as shown in Figures 1 and 2, comprises the relatively ring 13 and shade 11, or, it may be rectangular, and may embody various features such as switches, sockets, connecting mechanism and the like.

The plate and lamp socket receptacle 1() is formed to receive the electric lamp socket 14-, the lamp socket collar 15, and the electric lamp or bulb 16, the lamp socket collar and bulb being of the usual construction. The annular retaining ring 13 is permanently and securely fastened to the combined face plate and lamp receptacle 10 by means of a plural- 'ty of rivets 17, or in any other suitable inan- :uer. i

The shade 11 is shown with its lower portion 18 extending beyond the longitudinal central line of the lamp 16 to thereby furnish more shade tian would be the case, if the lower edge of the shade 11 was in line with the longitudinal central line of the lamp 1.6. Although the shade 11 has been shown with the portion 18 extending beyond. and below the longitudinal central line of the lamp 16, it will be understood that the shade 11 may be formed without the extended portion 18,

but with the lower edge in line with the longitudinal central line of the lamp or bulb 16. In some instances, it may be advantageous, from a manufacturing standpoint, to form an annular piece of metal into a cupped or dished-in portion and a suitable peripheral flange, and then cut or saw the metal through its central line and thereby produce two shades from the single piece of metal. in this form of shade it is obvious that there will not be an extended portion, such as the extended portion 18 referred to.

The electric light fixture may be mounted in a suitable receptacle or terminal box 19 set in the wall. T is fixture secured in the terminal box 19 by means of screws 20 and 21, which are countersunk in the combined face plate and socket receptacle 10 and X- tend through the inwardly projecting walls or sides of the terminal box 19.

As will be clearly seen from an inspection of Figures 1 and 2, the lamp shade ll'with its flange 12 may be rotated to any position desired. The shade is held between the face plate and socket receptacle 10 and the retaiiu iug ring 13 by having the shade flange 12 held in. the groove formed by the ring and plate. It will be noted that the retaining ring 13 is formed in such amanncr as to provide slot or groove 22 when it is secured in place to the face plate and socket receptacle 10, within which slot or groove, the flange of the shade may travel. It is essential that there shall be a friction fit between the movable shade 11 and its flange 12 and the stationary members 10 and 18, so that the shade 11 may remain in the position in which it is placed upon rotation, until it is desired to move it to some other position. lit will be understood that it is the primary purpose of the invention to have the parts constructed in such a manner that the shade 11 may be rotated and placed in any position, and that it will re main in that position until it is removed therefrom, as, for instance, by grasping the shade 11 and rotating it to a changed position. It will thus be seen that the shade 11 may be rotated at will to cause the rays of light from the lamp 16 to be reflected downwardly, upwardly, or to either side.

The light fixture as a single unit may be mounted in any suitable location on the wall, or, as shown in the drawings, it may be mounted in a suitable receptacle or terminal box 19 which l'ias been set in the wall. The light fixture is fastened and secured to the terminal box 19 by means of the screws 20 and 21, as above described. In order (0 place the screw 20 in position, the shade 11, with its attached flange 12, must be rotated a half turn until'the upper screw hole in the supporting wallv face plate 10 is seen to register with the screw hole in the upper part of the terminal box 19. The screw 20 may then be put into place, thus securing the supporting wall face plate 10 to the terminal box 19. ll henthis has been accomplished, the shade 11 may be rotated. a half turn to its upper position revealing the screw hole in the bottom of the supporting wallface plate 10 registering with the screw hole in the lower part of the terminal box 19. .he screw 21 may then be put into place. The fixture is now ready for use and the shade may be rotated in the manner set forth. 1

A further modification of the electric light fixture is shown in Figures 3 and l. The

structure, ashown in these figures, comprises the relatively stationary supportin wall face plate 23, the electric lamp and lamp socket receptacle 24:, and the rotatable annular apertured plate 25, to which is secured the lamp shade or cowl 26. The supporting wall face plate 23 is bent inwardly a sufiicient distance to enable the lamp socket receptacle 24 to be suitably secured to it. The receptacle 2a, which is cup-shaped and adapted to fit within the inwardly eiztending portion of the face plate 23, has ears orlugs 27 and 28 punched therefrom. The supporting wall face plate 23 and the lamp socket receptacle 2d are both apertured to receive the electric lamp socket 29, the lamp socket collar-.30, and the electric lamp or bulb 31.

The lamp shade 26 is permanently and se curely fastened to the rotatable annular apertured plate 25 by means of the plurality of rivets 32, or other suitable means The rivets extend through the flange 33 of the shade 26 and the rotatable annular apertured plate 25. It will thus be seen with this type of con struction, that the shade 26 and the plate 25 all 'ays rotate together.

The lamp socket receptacle 21 has an out wardly extending annular flange A p illrality of bolts and nuts 35; '36, 37 and 38 are disposed inf the annular flange 34. The flange" 34 and the plurality of bolts and. nuts 35, 36, 37 and 38 providea means whiclris the equivalent of a-groove for supportingthe ro tatable'annular ape'rtured plate25 and permitting the plate 25 and theshade 26'to rotate about the electriclamp 31.- The inner portionof the plate25'; at the aperture'in the plate, rotates between the outer portion: of the flange 34-and the nutson the bolts 36, 37 and 38; The bolts serve as shoulders or limiting stopsin therotation of the plate 25:

In assembling the form of light fixturelast described, the shade 26 is secured'to tlie ro tatable apertured plate 25 by means of the rivets'32passing throughtheplate 25and the flange 33. The lamp socket receptacle 24 is then passed into the aperture ofthe plate 25 with theannular-flange 34 against the inner portion of the plate 251 The bolts'and nuts 35', 36, 37 and 38 are then placed in position. The wall plate 23 is next attached to the cars 27 and 28 of the lamp socketreceptac'le 24 by means of the plurality of screws 39 and 40. The lampsocket 29, collar 30 and lamp 31, may be secured into position in the apertures of the lamp socketrecepta'cle 24' and the face plate 23. As thus assembled, the fixture may be mounted in the terminal box 41 set in the wall. The fixture is fastened to the terminal box 41 by means of screws 42 and 43 countersunk in the plate 23 andextends through; the inwardlyex'tending wallsof'the terminal box 41. In order to place the screw; 42 in position, theshade 26, together with the apertured plate 25', is rot-'atedahalf turn until the screw holev44- in the plate 25 registers with the screw hole in'the upper pa rt'of the suppoiting' xva'll'pl ate' 23 for the admission of the screw 42.- After the'screw 42 has-been put-in place, the shade 26 and attached plate 25 may be rotated a half turn until the screwhole 44 registers witlrthe screw hjolefin thebotto in part of the supporting wall plate 23 for the admission of the screw43. The fixture is now assembled ready for use'and the shade maybe rotated as desired.

Another modification ofthe invention will be found in Figures 6 and 7 of the? drawings. As shown in these figures, the electric light fixture comprises the rel atively sta tionary supporting wall plate 45 to which is secured by a plurality of screws, 46. 47, 48 and 49, or other suitable means. a flat, annular, aperture/d faceplate 50. Besides serving as a face plate,t'he plate' 50 functions as an electric lamp socketand electric lamp receptacle. The electric lamp socket 51,- having conductors 52 and 53,- and the lamp socket collar 54, are secured in theaperture of the annular face plate 50.- An electric light bulb '55 is fitted into the socket and collar:

Aflat", annular,'apertured ring-56is interposedbet'ween'the Wall plate 45 and the face plate '50; This ring:56 is held in position between the plates 45* andy50 respectively by means of the screws 46,47 ,,48- and49i The shade'57,which is prefcrablyopaqne and which ina'y ormaynofthave the extend- The electric light fixture of Figures -5, 6

and 7 maybe mounted in a' terminal box or other suitable receptacle whichmay be set in the wall, The fixtureis secured to the box by means of the screws 46 and 47 which extend through the inwardly projecting walls or sides of the box.

As'was described inconnection with the preceding structures, in order to place the screw 46in position, the-shade 57, with itsattached inwardly extending flange 58, must be rotated a half turn until the upper screw hole in the plates 45, and 50 and the intermediate ring: 56 are seen to register with the screw hole in the upperpart of the terminal boxGO.

The screw 46 should thenbe inserted into place, thfus securing the face plate 50, the ring-56 and the inner wallplate 45 into position on the wall {box or other receptacle. After thishas been done, the shade 57 may be rotated a half turn to-its upper position, revealing the screw hole in the bottom of'the wall face plate 50, which screw hole registers with the screw holes in theinner wall plate 45, the ring-56 and the inwardly extending flange of the wall box 60. After the screw .47 has been inserted into position, the fixture is ready for use and the shade maybe rotated'in the groove 59 to any position desired;

The moditiedelectric light fixture which is shown in Figures 8 and9 of the drawings, is identicalwiththe electric light fixture construction of Figures 5, 6 and 7, except asto the construction of: the outer face plate/correspondingto the outer face plate 50. The san c reference numerals will be used in connection with the modifications shown in Figures 8 and 9 as were used in: Figures cept as'to the outer face plate. I

The outer face plate 61, serving the same function as the plate 50 referred to, isprovided with the apertured angularly offset portion 62. Thetop' portion is indented inwardly as shown at 63, whereas the lower portion extends outwardly as indicated at 64. .The purpose ofthe offset arrangement ofthe also apertured and adapted to flange on said shade,

face plate 61 is to permit within its aperture 65 the inclusion of a larger sized electric lightsocket, and accordingly a larger sized electric lamp bulb than would be possible in structures like those of Figures 1 to 7 inclusive. The electric light bulbs inserted in the structures of Figures 1 to 7 inclusive must necessarily be small, since they must be inserted horizontally within the confines of the curved shades and the plates or socket receptacles of the fixtures. A large bulb could not be fitted into the light socket, since it could not pass the lower end of the shade and therefore of course could not be inserted into the lamp socket. However, with the offset arrangement of the face plate 61 a largeelectriclamp socket with a large lamp bulb may be used because they may be placed in position in the aperture 65 when the lamp shade is rotated downwardly one-half turn as shown in the dotted lines in Figure 8. After insertion of the lamp in place, the lamp shade may be rotated to its normalposition as shown in the full lines in Figure 8. After the light bulb has been inserted in position, the shade may be rotated to any desired position where it will be frictionally held as long as may be de sired. lVhen there is need of replacement of the light bulb because it has burned out or for any other reason, it will be seen that the light bulb may readily be removed by rotating the shade downwardly, extracting the used bulb and inserting the new one, and then rotating the shade to its former position.

Although not shown in any of the views of the drawings in this application, it will be understood that shims of suitable form and dimension, such as the shims 27 in my co pending application, may be employed between the rotatable and stationary members of the various constructions of electric light fixtures.

Having thus described the invention, what I claim and desire to secure by Letters Patent is:
